Does anyone have some life threatening mistakes he has made in the past and would like to share it here so people can learn from it and not repeat same mistakes? it will be fun lets help someone today.

I dropped out from my first year in the university to start a business hoping to be rich quicker, parents advised me to get back to school but i stubbornly refused. But now i am regretting it because i have discovered that business is not easy as i cannot face some life's challenges in business and cannot return to the university now because parents are late and i still have no money to help myself. So my advice to the young ones is they should stay in school and be focused. At least get their university education and so they will have arguably enough exposure to face life in the business or working world. what do you think friends?
